Unlock complete reportThe three-unit residential building at 4116 W Cornelia Avenue in Chicago's Irving Park neighborhood, owned by Konrad Kosciuk, was constructed in 1907 and has had relatively few documented service requests over the past seven years, totaling four. The most recent issues, recorded in early 2026, involve sanitation concerns including a code violation and garbage cart maintenance matters, both of which have been resolved. Of particular significance are two water-related incidents from late 2025, with lead testing visits conducted by the Department of Water Management in both October and December. While these tests suggest proactive monitoring of water quality, the presence of lead testing requests indicates potential concerns about the building's plumbing infrastructure. The property's service request history shows limited issues overall, with most matters appearing to be promptly addressed, though the age of the building and water quality concerns warrant attention.
